Sabino-white was one of the earliest dominant white alleles discovered, but was not originally recognized as such, hence the different name. They are homozygous for the dominant SB1 allele at the Sabino 1 locus, which has been mapped to KIT. Sabino-white horses are pink-skinned with all-white or nearly-white coats and dark eyes. Dominant white horses typically have white noses that can be subject to sunburn. While homologous mutations in mice are often linked to anemia and sterility, no such effects have been observed in dominant white horses. Researchers have suggested that at least some forms of dominant white result in nonviable embryos in the homozygous state, though others are known to be viable as homozygotes.

There are 32 identified variants of dominant white as of 2021, plus sabino 1, each corresponding to a spontaneously-white foundation animal and a mutation on the KIT gene. Dominant white has been studied in Thoroughbreds, Arabian horses, the American White horse, the Camarillo White Horse, and several other breeds. Some W alleles produce white spotting on horses with a predominately dark coat. However, much about the genetics behind various all-white depigmentation phenotypes are still unknown.ĭominant white (W) is a large group of alleles best known for producing pink-skinned all-white horses with brown eyes, though some dominant white horses have residual pigment along the topline. Depigmentation phenotypes have various genetic causes, and those that have been studied usually map to the EDNRB and KIT genes.

White colorings, whether white markings, white patterns or dominant white are collectively known as depigmentation phenotypes, and are all caused by areas of skin that lack pigment cells ( melanocytes). In contrast, grays retain skin pigment and only the hair becomes white. Some white horses are born with partial pigmentation in their skin and hair, which may or may not be retained as they mature, but when a white horse lightens, both skin and hair lose pigmentation. In contrast to gray horses which are born with pigmented skin they keep for life and pigmented hair that lightens to white with age, truly white horses are born with white hair and mostly pink, unpigmented skin. Many white horses have dark eyes, though some have blue eyes. White horses have unpigmented skin and a white hair coat.

True white horses have pink skin and white coats, and many have dark eyes, as here.
